Mark Shoen, a large owner in U-Haul International's parent company Amerco, heads a contingent of 10 Arizonans on Forbes' 2018 global-billionaire list.

The report released Tuesday listed 2,208 global billionaires, including 585 in the United States, the highest count of any nation. California led all states with 144 billionaires — more than any countries except the U.S. and China.

Some 256 global billionaires are women.

Jeff Bezos, the head of online-retail giant Amazon.com, ranked as the world's wealthiest individual with a net worth of $112 billion, followed by Microsoft co-founder Bill Gates at $90 billion and Warren Buffett, an owner and executive of conglomerate Berkshire Hathaway, at $84 billion.
